The Clinical Significance Of MRI Index Measurement In Cervical Spondylotic Myelopathy

Objective:To analyze the correlation of CSM patients differ in pre-operative JOA score and post-operative recovery rate with the MRI measurement indexes separatively. And discuss their clinical significance.Method:We retrospective analyzed 62 patients in whom CSM was diagnosed. And recorded the general data of patients, JOA score of pre-operation, JOA score of post-operation, clinical recovery rate etc. Measured and calculated the index-A, B, C and D by using the soft of Photoshop8.0.1 And then we analyzed the correlation of CSM patients differ in pre-operative JOA score and post-operative recovery rate with the MRI measurement indexes separatively by using the software of SPSS.Results:To analysis the differences of index-D between the two groups differd in JOA score of pre-operation by using the software of SPSS. It is found that P<0.05. And there was a correlation with Index-B, C, D and clinical recovery rate. The significance level of Index-D was 0.056. The regression coefficient was-0.259. The significance level of Index-C was 0.052, and the regression coefficient of Index-C was-0.269. The significance level of Index-B was less than 0.01, the regression coefficient of Index-B was-0.613.Conclusion:Our findings indicated that Index-D contributed to judge the serious level of CSM.There was a close correlation of index-D and clinical recovery rate.
